TROLLEY-SUPPORT FOR DOORS.

SPECIFICATION forming part of Letters Patent N 0. 447,505, dated March 3, 1891. I Application filed July 15, 1889; Serial No. 317,584. (ModeL) To all whom it may concern: door to be supported therefrom, is a trolley- Be it known that LLEMUEL COBURN, a cititrack C. The said trolley-track may be sezen of the United States, residing at Holyoke, cured on the under side of the heading, in in the county of Hampden and State of Maswhich case the door would slide between the 55 sachusetts, have invented new and useful Imwalls of the partition; or said track may be provements in Trolley-Supports for Doors, of secured in a vertical plane parallel with but which the following is a specification. somewhat removed from the plane of the door This invention relates to trolley-supports way, in which latter case the door would slide for doors, which doors are capable of moving closely along but outside of the partition. 60 1o longitudinally along or within a partition or Said trolley-track C consists of a tube, generother wall, the principal object of the invenally of a rectangular cross-sectional form at tion beingto provide means for the suspension its upper portion and having its lower edges or support of the trolley-track, from which turned in toward the median line and then through suitable roller-carriers and hangers turned upward, so that the bottom of the tube 65 r 5 the door is supported, which means are simhas the trough-shaped ways 6 b at either side ple and efficient with respect to the secure 0f the intermediate longitudinal opening 0. support of said trolley-track, and also permit The said trolley-track has devices for its supof adjustment of the track to level it; and the port and is supported thereon, as will be now invention consists in the constYuction and described. 7 2o combination of parts, all substantially as will D represents a bracket-casting of step form, hereinafter more fully appear, and be set by the upper horizontal portion 6 of which forth in the claims. it is secured to the heading, and when so se- Reference is to be had to the accompanying cured the other horizontal portion (Z stands drawings, in which this invention is illushorizontally and parallel to said portion 6 75 trated, and in connection with which the foland somewhat below the heading.

Figs. 4 and 5 are perspective views being larger than said perforation and servof parts employed for the support of the troling to support thereon the said end portion of 9 5 4 5 Icy-track, and Fig. 6 is a perspective view of the track, and said screw enters with a screwone of the hangers. engagement the under side of the heading; In the drawings, A represents a partitionor, more precisely speaking and as practiced, wall, having the doorwayB therein, of which the screw enters a screw-threaded bore 1' in a a is the upper casing or heading at which, metallic plate j, that is secured on the under I00 and also extended beyond to one side thereof side of the heading a, and said plate is proto an extent equal to the desired slide of the vided with check-pieces 7c 70, sufficiently separated to accommodate the width of the trolley-track between them and to serve as guards to prevent lateral movement of the end of the track adjacent thereto. The bracket-step cl at the other end is of such awidth as to closely fit between the side walls of the track, and thereby that end is also held against lateral movement. The said screw his turned to enter within the bore of the said metallic plate until the trolley-track has been leveled.

It will be apparent from the construction described that the trolleyt-rack may be maintained at a greater or less proximity to the heading, as required, and its position may readily be readjusted from time to time, as may become advantageous.

Each of the roller-carriers E employed in the present trolley contrivance consists of a pair of rollers separated corresponding with the separation of the troughways b, and auniting axle, said carriers being adapted to freely roll backward and forward in said ways. i

Each of the hangers consists of a horizontal barl disposed within and longitudinally of the trolley-track and to lie on the axle of the roller-carrier for its support thereby, and pending posts m m, to the feet or lower portions of which the door, by its upper edge, is secured. Said posts m between the bar l and l the top of the door are to be of such slight width as to freely pass through the longitudinal opening between the ways of the trolleyl track. In practice two hangers and a rollercarrier for the support of each hanger is provided; but, if desired, one hanger having its longitudinal bar about equal to the width of the door with two roller-carriers therefor may be employed with fair results.

A doorsupportcd, as described, from a trol- 4o ley-traclc may be readily slid alongside of a i wall or within such wall when it is made hol low, and, in conjunction with the adjusting devices for the trolley-track, the trolley form of suspension for doors becomes most readily adaptable for use in houses where the nearest approach to perfection in point of easy and true running of the doors is considered necessary.

' \Vhat I claim as my invention is 1. A wall or support having secured thereon a bracket-piece comprising, essentially, a longitudinal lug or extension (I, combined with a tubular trolley-track, substantially as described, having in the upper wall of its one end portion the screw f, adapted to be turned inwardly and outwardly through said upper wall and resting by its lower end on said extension (Z, and a supporting-stud at and for the other end of the tubular track and havin g a screw engagement for avertical adj ustment upon the wall or support, substantially as described.

2. The combination, with a bracket-step (Z and a plate j, having a screw-bore and provided with cheek-pieces 71; 7;, of the tubular trolley-track, substantially as described, provided at one end portion with a screw passing with an engagement through its upper wall and adapted to be turned inwardly and outwardly through said upper wall and to rest by its lower end on said bracket-step, and provided at its other end portion with a supporting-screw which passes upwardly through said track and with a screw engagement into said bored plate, substantially as and for the purpose described.
